Zika virus' effects are broader than first thought
The Zika virus is primarily known to cause microcephaly (small heads) in the babies of infected mothers, but its effects may be wider-ranging than first thought. A Harvard-led study has conducted brain scans of 45 Brazilian babies from Zika-stricken mothers, and the data suggest that even those children born without conspicuous problems may suffer later on. Ultimately, Zika is disrupting brain development -- microcephaly is a frequent result of that, but there can also be issues around the cortex (which is crucial to coordination and memory) that show up first and may only materialize on the outside as the child grows. Moreover, Zika can damage nerves in such a way that it forces arms and hands to contract.
